CS8078无法构建vSphere DLL：表达式太长或太复杂而无法编译

Question

我在此处按照文档进行设置以进行Microsoft C＃开发，并在此步骤中构建C＃vSphere DLL，在开发人员命令提示符中获得以下信息：

C:\Users\user\Downloads\VMware-vSphereSDK-6.5.0-4571253\SDK\vsphere-ws\dotnet\bin>build.bat

查看build.bat它似乎在此行上失败：

echo Compiling optimized VimService.dll
csc /t:library /out:Vim25Service.dll VimService.cs VimServiceSerializers.cs >nul || goto ERROR

如果我csc /t:library /out:Vim25Service.dll VimService.cs VimServiceSerializers.cs手动运行，则会得到以下信息：

C:\Users\user\Downloads\VMware-vSphereSDK-6.5.0-4571253\SDK\vsphere-ws\dotnet\bin>csc /t:library /out:Vim25Service.dll VimService.cs VimServiceSerializers.cs

VimServiceSerializers.cs(32548,98): error CS8078: An expression is too long or complex to compile

我也尝试过VS2017：

C:\Users\user\Downloads\VMware-vSphereSDK-6.5.0-4571253\SDK\vsphere-ws\dotnet\bin>csc /t:library /out:Vim25Service.dll VimService.cs VimServiceSerializers.cs

VimServiceSerializers.cs(31372,109): error CS8078: An expression is too long or complex to compile

注意，VimServiceSerializers.cs(#####,##)行和列上的行为每次都不同。

Google搜寻错误CS8078，发现这是编译器堆栈空间不足的问题。/sf/answers/571207661/

如何成功编译VmWare的代码？

Answer 1

我想到了。序列化器 CS 文件具有长时间不间断的子句if ... else if ... else if ...。编译器必须立即处理整个 if/else 表达式，这会导致堆栈空间不足。

幸运的是，这些中的每个分支都else if以一条语句终止return。这使得所有else ifs 在功能上等同于独立if语句，它们是独立解析的。

在多处进行替换后，文件将进行编译。这是我修改后的 VimServiceSerializers.cs：https://1drv.ms/u/s!Al6mzY0CpY7EnHqBRDyg -z0ctrjk
